Sweet Potato Cake

Preheat the oven to 180 C / Gas 4. Grease and flour a 23x33cm or similar sized baking dish.

Stir together the sugar and vegetable oil in a large bowl until smooth. Beat in the eggs one at a time, then stir in the vanilla and sweet potatoes.

Combine the flour, baking powder, bicarbonate of soda, salt and cinnamon in a separate bowl; stir into the batter 250ml at a time, alternating with the beer just until everything comes together. Spread the batter evenly in the prepared dish.

Bake for 35 minutes in the preheated oven or until a knife inserted into the centre of the cake comes out clean. Cool completely before frosting or serving.
